An Eotech’s center dot is diffraction limited, e.g. as small as a red dot can possibly be, due to the way it is generated. For people with average eyes, that will be perceived as ~1 MOA, although it will be even sharper with a magnifier or with above-average vision.
I run 3 MOA on all my red dots, but I have astigmatism, so they all look like 10 MOA dots shaped like Elmo.
Red dots are poor at target shooting.
Exact opposite of mine and dozens of others experience with them.
Us with older eyes find that our groups magically shrink when using a red dot compared to iron sights.
My Glock G19 MOS will do maybe 2" at 25 yards with factory sights. But with a Burris Fastfire III installed, it will do 1"...

Interesting.
I've been toying with the idea of placing a dot on my Browning automatic .22 break down rifle for plinking uses. I have an Aimpoint H2 with 2MOA I need to wring for groups.
I poo-pooed the idea of red dots for a long time. Saw them as unnecessary tactical doo-dads for mall ninja warriors. Then I bought a cheap one off of Amazon for under $50 to try on a pistol. It worked! Bought a nice $200 Burris model and was amazed at how much my groups shrunk.
They are like Viagra. They help older gentleman perform like they did 20 years ago.

They are designed to give a fast sight picture and excel against moving targets.
